PNEUMATIC TIRE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 672,073, dated April16, 1901.

Application filed September 27, 1900. Serial No. 31,237. \No model.)

To wZZ whom it may concern:

Be it known that I, HUGH L. WARNER; a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Pneumatic Tires forVehicles; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form apart of this specification.

This invention relates to improvements in pneumatic tires for vehicles,and more particularly to tires of that class in which an innerinflatable tube is inclosed within an outer casing detachably secured tothe rim of a wheel.

The invention consists in the matters hereinafter described, and morefully pointed out and defined in the appended claims.

In the drawings, Figure 1 is a fragmentary perspective view of a tireembodying my invention, showing the same as attached to a wheel-rim.Fig. 2 is an enlarged cross-section of the same. Fig. 3 is a view ofaflexible strip forming part of the attaching means. Fig. 4 is afragmentary perspective View of the outer casing. Fig. 5 is a view incrosssection of a modification of the attachingstrip.

In the drawings, A indicates a wheel-rim of any desired construction.

B indicates a flexible strip or band provided adjacent to both edgeswith studsb b and secured circumferentially on the rim.

0 indicates the outer casing, adapted to be secured by its edges to thestuds b b and to inclose the inflatable inner tube D.

The flexible strip B, as shown, consists of a strip of fabric coated onone side with cementing material, such as rubber or the like and foldedlongitudinally, as illustrated in Figs 2 and 3, with the cementedsurfaces turned inwardly and inclosing transverse struts b'b. Saidstruts are spaced equal distances apart and are each provided at eachend with an integral stud b, which projects through the upper surface ofthe strip, as indicated in Fig. 1, and aifords means for at- Said studsb are, as shown, slightly upset at their outer ends, at the inner sidethereof, thereby providing a slight lateral projection at the top ofeach stud, which aids in retaining the outer casing in place. Thetread-surface of wheel-rims as ordinarily constructed are cylindricallyconcave in cross-section, and when rims are so constructed the strip, asdescribed, may be nailed, screwed, cemented, or otherwise secured tosaid rim. If, however, the surface of the rim is not cylindricallyconcave in cross-section, the under side of the strip may be adapted tofit in the rim by providing a backing of fabric or other desiredmaterial of the proper shape, as indicated in Fig. 5, which illustratesa form suitable for use for the Dunlop rim.

The outer casing 0 consists of an endless tube of rubber or othersuitable material of a desired size slit circumferentially on its innerside and provided along its slit edges with eyelets a, spaced tocorrespond with the studs on the flexible strip B and adapted to engagethe same. On the inner side of said casing a reinforcing-strip c issecured adjacent to each of said edges and covering said eyelets, asindicated in Fig. 2. Said reinforcing strips are adapted not only tostrengthen the cut edges of said casing, but also to act to prevent theheads of said studs from coming in contact with and chafing the innertube D. The outer covering of rubber of said casing extends to a pointadjacent to said eyelets and terminates on each side in a flap or fold 0adapted when thecasing is secured upon the rim,'as indicated in Fig. 2,to form a contact-surface with the rim and the edges of the flexiblestrip considerably increasing the thickness of said casing at said pointand acting as a rub-surface to prevent chafing of the casing on the rim.

The operation of my device is as follows: The flexible strip B is firstsecured on the tread-surface of the rim circumferentially thereof, withthe studs b b projecting outwardly, as indicated in'Fig. 1. One edge ofthe casing is then secured on the studs on no side of said rim and theinflatable tubeo'is placed therein. The other edge of said casing isthen secured upon the remaining studs, thereby drawing the edges of saidcasing together and forming a continuous outer tubeinclosingtheinflatabletube. Saidinnertube is now inflated in the usualmanner to the desired tension, with the effect of expanding the outercasing and firmly securing the same in contact with the rim, asindicated in Fig. 2. Obviously many details of construction may bemodified without departing from the spirit of my invention.

I claim as my invention 1. A detachable tire for vehicle wheelscomprising a flexible strip provided on one side with studs and adaptedto be secured circumferentially on the wheel, an inner tube and an outercasing inclosing said inner tube and provided atits edges with eyeletsadapted to engage said studs.

2. In a detachable tire for vehicle-wheels a strip of fabric coated onone side with adhesive material and folded longitudinally with thecoated surface turned inwardly, struts secured transversely between thefolds and provided at each end with a stud projecting through thefabric.

3. A vehicle-tire comprising a flexible strip adapted to be securedcircumferentially of a Wheel-rim and provided along each edge with studsrigidly connected in pairs, an inflatable tube, an outer casingcomprising an annular band of fabric provided adjacent to each edge witheyelets adapted to engage said studs and forming when secured thereon acontinuous tube inclosing said inflatable tube, each of said eyeletsbeing closed on its inner side.

4. In a device of the class described, an outer casing comprising anendless strip of fabric provided adjacent to its edges with eyeletsadapted to engage studs secured along the circumference of a Wheel-rimand forming when so secured a continuous tube, a strip of fabric securedalong each edge on the inner side of said casing and covering saideyelets and resilient flaps or folds on the outer side of said casingadjacent to the eyelets and adapted when said outer casing is securedupon the wheel-rim to form a cushion between the casing and the rim.

5. In a detachable vehicle-tire the combination with a wheel-rim of astrip of fabric narrower than the wheel-rim and secured centrally andcircumferentially thereof,said strip being provided with studs equallyspaced upon the outer side of the rim, said studs be-- ing connected inpairs on opposite sides of the strip, an outer casing comprising acontinuous band of fabric provided adjacent to its edges with eyeletsadapted to engage said studs and forming when so engaged an endlesstube, a strip of fabric covering said eyelets on the inner side of thecasing and longitudinal resilient folds or flaps integral with thecasing adjacent to said eyelets, said folds or flaps engaging the edgesof the rim and strip and acting to prevent wear on the outer casing.

In testimony whereof I have hereunto subscribed my name in the presenceof two subscribing witnesses.

HUGH L. WARNER.
